Which statement best describes how electrons are organized in the electron cloud of an atom?
A
Electrons occupy specific energy levels and subshells according to the Aufbau principle, Pauli exclusion principle, and Hund's rule.
B
All electrons are found in the nucleus along with protons and neutrons.
C
Electrons are organized only by their atomic number, regardless of energy levels or subshells.
D
Electrons are randomly distributed throughout the electron cloud without any specific arrangement.
Verified step by step guidance1
Understand that electrons in an atom are arranged in a structured way within the electron cloud, not randomly or all in the nucleus.
Recall the Aufbau principle, which states that electrons fill atomic orbitals starting from the lowest energy level to higher ones in a specific order.
Consider the Pauli exclusion principle, which says that each orbital can hold a maximum of two electrons with opposite spins.
Apply Hund's rule, which explains that electrons will fill degenerate orbitals (orbitals of the same energy) singly first, with parallel spins, before pairing up.
Combine these principles to conclude that electrons occupy specific energy levels and subshells in an organized manner within the electron cloud.
